QSRC series - technical specification

QSRC series - introduction

The balanced cartridge seal design uses less power and therefore less fossil fuels to drive it than is required by standard unbalanced seals and only 20% of the power requirement of pump packing. As leakage is eliminated, corrosion problems to pump, bearing and pump room are all greatly reduced.

All packing must leak to survive, whereas seals should be leak free. This reduces environmental contaminants and disposal costs.

All the QSRC Single Rotary Cartridge Seals can be fully refurbished with most parts being “re-used”

The QSRC series including type A and type B are designed with a Carbon restriction bush which is hydraulically loaded upon seal failure and acts to restrict product leakage to the environment. Also incorporated into the type B version is a drain port to take away product leakage to a safe area to be disposed of or recycled.

The type C cartridge seal incorporates a back-up seal to reduce fugitive emissions of noxious products into the environment.

The type D cartridge seal incorporates a low pressure external mechanical seal to reduce fugitive emission of noxious products into the environment.

Anti clogThe dynamic o-ring moves

onto a clean area as seal faceswear. Components remain free for

longer seal life.

No fretting of pump shaftThe seal internal o-ring is

static on the shaft and is guaranteed never to fret

the pump shaft or sleeve.

Springs out of fluidThe Alloy 276 springs are not

in the pumped fluid wherethey could corrode or clogand so remain effective for

the whole of the seal life.

Low turbulence wetted partsThe smooth contours of thewetted surfaces create very

little turbulence within the sealcavity for longer lasting seal

components in abrasive mediause.

Restriction bush(regular, type A and B)The Carbon restriction bush serves three purposes: to centre the gland on the shaft, to set the seal to the correct working length and to restrict leakage when the seal eventually wears out. The bush is passive until the leaking product pressure hydraulically loads it restricting emissions to the environment.

Flush(type A, B and C only)

The flush connection allows the pumped fluid to be circulated

from pump discharge to the seal, from seal to pump suction, or

into the product from a higher pressure external source.

Quench and Drain(type B, C and D only)Connections allow control of the environment around the seal by quenching the seal and providing a drain for both quench media and seal leakage.

External lip seal(type C only)A conical lip seal (0.1 bar / 1.5 psi) allows a low pressure convection tank to be added, which protects the faces from crystallisation, vacuum and dry running.

Buffer Fluid seal(type D only)An external low pressure (2 bar / 30 psi) seal designed to reatin the buffer fluid and provide effective enfironmental control after internal seal failure. The seal also sets teh correct working length and centres the gland during installation.

Self aligning stationaryThe patented self aligningstationary eliminates fretting and spring fatigue, ensures good alignment of seal faces and provides a good ‘heat sink’ for cooler running with heightened face lubricity.

External clampingThe seal is automatically set tocorrect working length with theexternal drive screws. Nomeasuring or clips are required.

BalancedThe seal is hydraulically balanced to achieve optimum face loading for high pressure capability and to provide cooler running for longer seal life.
